Add AppendInto function (#31)

This adds an AppendInto function that behaves similarly to Append
except, it operates on a `*error` on the left side and it reports
whether the right side error was non-nil.

    func AppendInto(*error, error) (errored bool)

Making the left side a pointer aligns with the fast path of `Append`.

Returning whether the right error was non-nil aligns with the standard
`if err := ...; err != nil` pattern.

-if err := thing(); err != nil {
+if multierr.AppendInto(&err, thing()) {
